Is that required to get the error?

Everything looks OK in the systemInfo. Have you tried a Reset?

3

After i ve seen the error and restarted everything
Sorry I can not share a repeatable way to reproduce.. .
But it s not the first time I get this

Tom,

Those errors are indicative of a networking issue. If this is on a corporate network get your IT guys involved. If this is on a personal network start by unplugging and replugging any data cables to be sure you have good connections. Then look at router and pc logs for error messages.

However, bear in mind that there was massive internet disruption yesterday because of the Amazon DNS issue - you could be seeing fallout from that. Maybe pause diagnosis until you see if the problem continues…

Regards
Jeremy

This happened to me as well while I was working offline (I was on a train with no internet connection):

This deluge of network errors (one every 2 minutes) shouldn’t be normal behavior, even offline. I don’t remember this in earlier versions (I am using Rhino 8 SR 24 on Windows).

Hi Alessio -

I turned off wifi on my computer and did stuff in Rhino for a longer period of time. I’m not getting those error messages here.
Could you please run the Rhino SystemInfo command and copy-paste its output here?
-wim

Sure, here it is

Hi Alessio -

Thanks.
Can you reproduce that behavior by simply turning off your internet connection and waiting two minutes?
If so, is that still the case after disabling Karamba and restarting Rhino?
-wim

I just did the test: the behaviour reappeared right after turning off my wifi, and persisted after I disabled the only Karamba-related plugin I saw in the Plugin manager and restarted Rhino.
